  • Lowest effective % for exfoliation with salicylic acid

    Posted by JonahRay on November 25, 2021 at 7:06 pm

    Hey friends,

    I’m wondering if anyone knows of some papers, or knows themselves, what the lowest effective dose for exfoliation with salicylic acid is. I’ve seen products as low as 0.5% upwards of 2% (as regulated by most jurisdictions).

    Any info or insight would be helpful!

    The range 0.5% to 2.0% is specifically for products regulated as OTC acne products.

    If you are looking to market an SA Exfoliation product that is not OTC acne, Paula’s Choice 2% SA Exfoliating Solution is the brand’s top selling product globally.  That’s what you would be competing against.
